I would recommand you to have a look at Intego Personal Backup. After  
the first backup (which takes quite some time) every other backup  
will only copy new and changed files. If you run it daily the whole  
thing should not take more than 10 -15 minutes.
Secondly, it gives you the option of syncronizing two different macs.  
Although I have not tried this yet, it might take care of your mail  
problem. You can get a free trial version with all features on the  
Intego website and later upgrade it to the full version if desired.  
It seems to be a bit more expensive than similar software (never  
tried SuperDuper) but I am more than happy with it.
